IMPROVEMENT IN HUBS FOB. CARRIAGE-WHEELS.

TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be'it known that I, HARVEY D. HAlthDEN, of Hartford, in the county of Windsor, and State of Vermont, have invented 'a new and usefui Improvement in the Hubs 'ot' Carriage-Wheels; and I do hereby declare the salinehto be fully described in the following specification, and represented in the accompanying drawings, of w x0 v Figure 1 is a top view,

Figure 2 a longitudinal section, and r I Figure 3 a transverse section of a wheel-huh constructed in accordance :with myinvention, and as ready for the reception of the sleeve or box of an axle.

The hub, as shown in the drawings, is composed of a middle part, A, of cast metal, and two portions, B B,

of wood, the latter' being secured in sockets formed in the part A.

The said part A is composed of two flat and parallel and perforated disks, a a united'by a series of radial connections, 6 6, arranged at equal distances apart, and inman'ner, with respect to the disks, as shown in the drawings.

From the outer face of each disk a ring, 0, projects concentrically with the disk, so as to form on the. side of the disk a socket, 0Z,to receive one of the end parts, B, which is turned so as to enter and fit closely to such socket, and may be-seeured-thereto by means of screws,f, going through the ring and screwed to-the wood. f The spaces 9 9 between the two annuli and their radial connections, aredesigned to receive the tenons of the spokes, which may be made in breadth and width nearly if not quite equal to the baselportions of the spokes.

The above mode of making a hub ready for reception of the sleeve, .rendersthe hiib very strong, and not only prevents the wooden parts fromsplitting, but supports the spokes'to greatadvantage. It is far preferable to a. hub made either wholly of metal or wholly of wood, which I do not claim.

I am aware of the inventions described in the United States Patents, Nos 65,257 and i'4,117, which represent an open frame of metal, composed of two annuli arranged parallelto'eaeh other, at a short distance apart, and connectedhy metallic bars extending from one to another; the whole being to be driven on a wooden cylinder or hub, and to receive and hold a series of spokes tenoned into such cylinder. I

My invention differs from this hub and spoke-supporter, inasmuch as, instead of two rings, I employ two .disks connectedfiy barsiand having a cylindrical socket on .the outer face of each disk, the sockets being to hold two separate cylinders or pieces, B B, of. wood, which are to receive an axle-box.

With my invention the spokes arewholly supported by the metallic disks, and are not tenoned into a wooden cylinder. The disksat their centres are to be bored to receive the axle-box, and they serve, with thewooid portions B B, to sustain'it,

Furthermore-thedisks, by extending across each of the socket-rings, form shoulders to support the ends 7 of the pieces B B. With my improvement, the spokes are entirely insulated from the wood for sustaining the axle-box, and thus, while the wheel may be in use, they cannot operate in any way to loosen the con'nection of the parts A-B'B, by which the box is supported.- I

I therefore make no claim to theinvention described in either of such patents. I claim the improved supporter, A, or arrangement of disks, socket-rings, and radial c setforth.

Also, the combination and arrangement of the two separate cy disks, the socket-rings, and these radial connections, arranged togetherand c collections, as

est in one piece,'as set'forthl HARVEY 1). HARADEN, Witnesses:
